"Application filed September 5.1907. Serial No. 391.459.

. To all whom it may concern:

Be it known that I, EDWARD PAUL GUEN- THER, a citizen of the United States, and a resident of West Hoboken, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Machines for Exerting Pressure, of which the following is a full, clear, and exact descrip tion.

My invention relates to mechanism for exerting pressure, being adaptable to I devices varying considerably in function, and the purpose of the invention is to provide a simple and economic device for exerting pressure upon gaseous or liquid substances,

eing particularly serviceable as a pump to be used in connection with automobiles, and

like motors, or'for propelling vessels.

The invention is also applicable for usein hotnhouses andfor drainage purposes genera y.

It is a further purpose of the invention to provide a device of the character described that will admit of a free passage of liquid through it no matter in what osition the pressure exerting plate or bla e may be;

and it is also a purpose of the invention to so construct the device that the pressure exerting blade can be quickl changed so as to alter the direction of t 1e delivery of the water.

f The invention consists in the novel contion, in which similar characters of reference indicate corresponding parts in all the figures. Figure '1 is a section through the conduit illustrating the pressure exertingblade in a longitudinal edge view, the section being taken practically on the line 1'1 of Fig. 2; Fig. 2 IS a section through the conduit taken at an angle to that. shown in Fig. 1, and practically. on the line 22 of Fig. 1; Figs. 3, 4, 5, and 6 are sectional views illustrating 'the positions of the ressure exerting blade during'one cycle, or uring one revolution of the eccentric controlling the said pressure exerting blade.

A represents a conduit, tan-gular in cross section, an

(preferably re oin' the present instance constituting the casingfor thepump.

The conduit is provided with an inlet 10 at one end, and a discharge 11 at the opposite pulley, whereby the shaft may end, and-1n operation is usually tplaced in a tank of still water, but it may receive its supplyin any desired manner. An opening 12 is made in one side surface of the conduit A covered by a journal box 13 having a suitable gland 14, and a shaft 15 is passed through said gland and journal box, being provided atits outer end with a ear 1-6 or e driven from any source of power. A crank disk 17 is secured to the inner end of the shaft 12, being fitted to turn in a seat 18 produced in the bottom of the journal box, as is shown disk extends by preference substantially to the opposite side of the conduit, as is also tut-es the pivot and operating factor for the pressure exerting plate or blade B provided etween its ends with a bearing 20 for the said crank pin 19. The longitudinal edge of the blade closely approaches the opposing inner faces of the conduit, as-is'also shown in Fig. 2, and that section b of the blade B that extends in direction of the outlet 11 of the conduit, is made longer than the section excess of leverage overthe receiving section I), but both ends of the blade or plate, B are well within the conduit.

The operation of the device is very simple; supposing the first position of the blade or plate B to be that shown in Fig. 3, wherein it lies parallel with a side of the conduit, the crank disk 17 being revolved, the next position of the blade orplate B will be that shown in Fig. 4, wherein it assumes a diagonal position relativel to the conduit. sectionb of the blade or plate moves quicker than the longer section b, and provides for a volume of water between the longer section b and the opposing side of. the conduit. In the next position of the plate or blade it lies parallel with the opposing side of the con duit as is shown in Fig. 5, and in assuming this position the lon er'end of theiblade or plate B moves quic y and forcibly the water, causing it to be ejected at the delivery end ofthe conduit in such a manner that none of-the water can flow back of the bladea half cycle, and it may be observed that as the longer end of'the b ade produces the exin Fig. 2, and the crank pin 19 of the said shown in Fig. 2. The crank pin 19 consti The shorter The movements just described,constitute ipelling action described, the shorter end of b that extends in direction of the inlet 10, so that the discharge section b has a greater a ainst I the blade will bring about a suction action. After the blade or plate B has assumed the position shown in Fig. 5, it is next carried to the diagonal position shown'in Fig. 6, the reverse of that shown in Fig. 4, and then assumes' its initial position shown in Fig. 7. Thus it Will'be observed that during a cycle the blade 'or plateB bringsabout two discharge actions and simultaneouslytwo suclilQIlflOtlOIlS. Since .the plate or blade B is pivoted upon the crank pin 19, the water is iree if the pressure is strong enough,'to pass ing sald blade'transversely to the conduit.

and means eccen-.

conduit, a bladetherein, a support eccentrically connected with the blade, and means for revolving the support.

3. In a mechanism for exerting pressure, a conduit, a pressure exerting blade disposed within the same, and provided with 'a bearone end thanthe other, and an actuating. device comprising a crank disk and a driving mechanism therefor, a pin bearing of the said blade, the said blade being unsupported between itsbearing and its ends.

4. Ina mechanism for exerting pressure, a conduit, a pressure exerting blade disposed therein, and a single actuating'means for pivotal connection with the said blade at a i point'between its ends, one endof the blade being longer than the other pthe said blade being reversibly located. within the conduit.
